AT5 timing pulley bar stock

AT5 timing pulley bar stock consists of bars with teeth for an AT5 belt with a 5 mm pitch. The wider, reinforced tooth carries higher loads than the T5 profile at the same pitch, which is why AT5 performs well in precise axis drives, sliding tables and automation.

AT5 timing pulley bar stock - several pulleys from one bar for small batches

You can make several pulleys of different widths from one bar, which lowers the cost for small batches and prototypes. Aluminium is easy to cut and bore, and a light pulley supports dynamic axis operation. The AT profile maintains positioning accuracy well, so the pulley performs well in linear drives.

AT5 bar stock vs T5 belt - questions and answers

Does AT5 bar stock fit a T5 belt?

No. The 5 mm pitch is the same, but the AT5 tooth is wider, so a T5 belt does not seat correctly in AT5 grooves.
